One4Life takes your child from birth to big kid, surrounding them with trusted Britax safety. It easily converts from a rear-facing infant car seat, to a forward-facing 5-point harness seat, to a high-back belt-positioning booster seat. A high-strength steel frame, crumple zone, and V-shaped tether help absorb crash energy. Features ClickTight® technology for struggle-free installation and a SafeWash® cover with no added flame-retardant chemicals.
